HOW TO MEASURE YOUR REQUIRED SIZE
A - OPENING WIDTH (THESE MEASUREMENTS ARE THE OPENING IN THE BRICKWORK)
STEP 1 MEASURE A - (WIDTH) (THEN ADD 150MM (75MM per side) TO THE WIDTH TO PROVIDE SECURE FIXING IN TO SOLID BRICK).
STEP 2 MEASURE YOUR HEIGHT NEEDED (you do not need to add any to the height)
STEP 3 WHEN YOU HAVE YOUR WIDTH AND HEIGHT YOU CAN ORDER THE CLOSEST LARGER WIDTH (E.G. if your door width was 1010mm you would then add 200mm making it 1190mm so you would want 1200mm width grille).
